The correct sequence in decreasing order of pH ,cr5 m4u.ht/xy3vrr*6o ;05ru9e be d sahggm for equimolar solulnr eznu y058h)7/ ckstions is:
A. $CH_3COOH \gt HCl \gt NH_3 \gt NaOH$
B. $HCl \gt CH_3COOH \gt NaOH \gt NH_3$
C. $NaOH \gt NH_3 \gt HCl \gt CH_3COOH$
D. $NaOH \gt NH_3 \gt CH_3COOH \gt HCl $
参考答案: D
本题详细解析:
NaOH is a strong base and has ainsls 8)mj56vhmu )0b high pH,$NH_3$ is a weak base with a lower pH than NaOH.$CH_3COOH$ is a weak acid, HCl is a strong acid and so has the lowest pH.
